-20y+30-y=-4\left(y-2\right)
Use the distributive property to multiply -5 by 4y-6.
-21y+30=-4\left(y-2\right)
Combine -20y and -y to get -21y.
-21y+30=-4y+8
Use the distributive property to multiply -4 by y-2.
-21y+30+4y=8
Add 4y to both sides.
-17y+30=8
Combine -21y and 4y to get -17y.
-17y=8-30
Subtract 30 from both sides.
-17y=-22
Subtract 30 from 8 to get -22.
y=\frac{-22}{-17}
Divide both sides by -17.
y=\frac{22}{17}
Fraction \frac{-22}{-17} can be simplified to \frac{22}{17} by removing the negative sign from both the numerator and the denominator.
